the cars are to be used for other purposes; and the opjects of my improvement are comparative inexpensiveness of manufacture, durability facility in use, sim plicity of construction, and to provide a door of this class that may be easily opened'and will not stick by reason of the grain working between the joints, that will not leak grain, and that isperfectly secureagainst bursting out. These objects I attain by ineansoi the mechanism illustratedin the accompanying drawings, in which i i Figure 1 is afront elevation of the door closed; Fig.

2 is a front elevation of the door with the nether section open; Fig. 3,.a detail of the lock; Fig. 4, a sectional detail of the lock on line A B of Fig. 3; Fig 5, a vertical section of the door closed; Fig. 6, a transverse section of the door open, folded, and hung from. the roof of the car; Fig. 7, an inside or rear elevation-of the door closed.

Similar reference characters refer to similar parts throughout the several views of the drawings.

The body of the'invention consists of sections 1, 2,: and 3 of the door, which extends a suitable height for the purpose of holding grain in the car inthe usual way, but does not close the entire opening. The upper section 1, and the middle section 2 are made of sufli- 'cient length to extend across the opening and lie against the inner face of the door-posts 23. The lower section 3 is of such a length as to pass freely between the adjacent faces of the door-posts 23, leaving the inner faces of the posts exposed. Sections 1 and 2 do not extend entirely .40 across the inner faces of the door posts 23-, and the outer edges which are not covered by the sections are faced with pieces 22 which are of approximately the same thickness as the sections of the door where they come in contact with the ends oi the sections, and are-tapered oh from the door. Atsection 3, the iacingpieces 22 are broader than above and cover the entire inner laces oi the posts. Pieces 22 forrn end braces for the door sections, and also serve as guards to prevent grain from gettingbehind the door sections. Theentire door is adapted to swing inward, being hung on hinges 14. The tree leaves of the hinges are made of sufiicient length to extend some distance. across the upper set 'tion 1 of the door and are rigidly securedthereto, The

free leavesare offset at their pivots so 'thattheyextend l, straight upward, leaning a clear spa'ce-.between- 1911 1;

insertedover' section 1 to close up the remaining open space when deemed necessary. Sections 1 and 2 are joined together at their :rneeting page. by means of ordinary-strap hinges 18 placed on the battens 4 on the inside of the door. hdapts section2 for inward relative to section lior the hereinafter Sections 2 and 3 are joined together at their edges, ordinary strap hinges l9 placed on theoutside oi the'door, adapting section 3 to swing outward for the purpose hereinafter de- To prevent section 3 from swingingout'ward when the w n loadedwith grain, cleats Tare provided, in bear against its entire width, and pivoted at their upper ends on 'bolts13, so that tholower ends of the cleats may be free to swing outward. Bolts 13 are disposed just above the line of hinges 19, so that section 3 m swing out ireelywhen the cleats 7 are released and free to swing out.

Bolts 10 are placed near the lower ends ofdoor-posts 23 and let into the surface of the posts so that they are flush with the outside of the car and will not interfere with the passage of the outer car door. Each bolt 10 l is provided at its free end with a right-angular hook portion 8 and at its opposite end with a siniilnr right angular hook portion 9. The-two right'engular hook portions of the bolt extend at an angle of relative toeach other. Bolt 10- is secured by means of double plates consisting of an outer plate 11 and an inner plate 12 which has a groove 21 iormed in it to accommodate 4 the bolt. The inner'plate 12 is shorter than the outer plate 11, but is brought out flush with the, outer edge I of plate 11. The inner hook portion 8 of 10' stri kes against the rear edge of plate 11 when the bolt is'shot out into full operative position. When hook-portion 8 is turned inward intoicontact with the exposed face 'of cleat 7 (Fig. 3), the portion 9 extends downward I and presses against the inner side of outer plate 11 be low the axis of the bolt, so that its rotary motion is limited and stopped when 8 extendsacross cleat 7 at right angles thereto. .When the bolt is drawn back to release cleat ,7 part 8 is turned over through 180 degrees so that it extends outward, 'Part 9 will now be turned upward and rest against the inner side of plate 11 above the axis of the-bolt, and the further rotary motion of the bolt will be stopped. The bolt may now be drawn back so that part 8 recedes. into the recess provided therefor in the outer edge of plate 11. It will he un 'derstood thati the-boltlo must be shot to the closing position (Fig.3) before thetouter door of the car can he Bolts 10 are also for the purpose of locking cleats! in a vertical position against the adjacent faces stemme- 41; .plate 15, consisting of a plate with a slot in the and; is secured on part 1 of thedoor, and extends downwsrd ao as to lap. over part 2 brace it. When the door is folded. (Fig. 6)the eye in plate sexposed'. A hook, 17, is swung from-the ceiling of the car in such a position as to enter the eye in plate 15rd the purpose of holding the door near the ceiling when not in-use'.

The operation of my new grain door will now be understood. To use the'door, it is swung down across the portal, as shown in Figs 1, 2, 5, and 7,, so that section 3 lies against the inner edges oi cleats 7, and sections l and 2 lie against the inner faces of posts 23.. Cleats 7 are pressed in against the ends of section 3 andlocked in that position by means of bolts 10. In order to lock the door, bolts 10 are shot across cleats 7 and portions 8 turned inward so as to point toward the door. It willbe understood that in this position the bolts not only hold cleats 7 firmly against section 3, but, the hook parts Sat the same tirhe hold cleats 7 firmly against the adjacent faces of door-posts 23, so that any leak- .age, of. grain between cleats 7 and the door-posts is prevented. Tlie hook portion 9 of the bolts pre- 1 vents them from pulling out of their sockets'or turning more than a hali revolution. Sections and? of the door, beingflonger than. section 3, extend across and rest against the inner faces of posts 23. The door it now in a .position for loading the car with grain. Is

. will be und 'tood that, as the car is filled the grain will press againstsection 3, so astopress it firmly against. cleats 7, so that no grain can work in between section 3 and cleats 7. Sections 1 and 2 are also pressed firmly against the inner faces of door posts 23;. so that the grain cannot get betweenthemfandthus the in ward pressure'o'fthe grain against the door tends to seal the door and prevent leakage at any point, making 9.;

strong, perfectly secure door. When the .car.is to be unloaded, it is simplymeeecsary toturn bolts 10 a half revolution, so that'por'tions'l ektend outward, and,

- from bolts 10, section 3is tree to swing outwardand then push bolts 10 back till parts 8 enter the recess in plate 11 so as to release cleats 7 If bolts 10swork hard, they may be drivenv back with a stone or any available implement. .As soon as cleats 7 are released will immediately do so on account of the pressure of the grain against it. n section a should stick, a slight I 14 toward the ceiling of the car until it reaches the position shown in- Fig.- 6. Here it may be secured by inserting the free end of book 17 in the eye provided in plate 4. The door is nowout of the way, and the remaining grain in the car may be easily unloaded, and the car may be used for any other'purpose desired,

leaving the door ready for use when required. It will beseen that itiis not necessary to use any nails .to secure the door, thus avoidi'ngthe usual injury ,to cars and therefore rendering them'more durable. It will be understood that when bolts 10 are shot into the position shown in Fig. 1, they are flush with the outside surface-of the car, and the regular door may be closed without interference. v I j r Having thusdescribed my invention so that anyone skilled in the art pertaining thereto may make and use A grain door for box cars, adapted to swing inward bodily from the threshold to the ceiling of the car, comprisirlg in combination an upper section extending across thefdoor frame resting against the inner faces of the door posts, and hinged to the top of the door frame in 'such amanner as to swing inward;

a middle section extending across the door frame, resting against the-inner faces of the door posts. and hinged to said upper section so as to swingv inward relative thereto; and a nether section-of such' a length as to pass freely between the adjacent faces of the door-posts and hinged to saidmiddle section so as to swing outward relative -thereto, substantially as and for-the purpose specified.
